I have not ran numbers but if you have a second hard drive you might want to create a scratch drive on it for Camtasia to use. I can't verify this yet but I'm betting it changed the default you may have used on 9.1.

Serial drives like the one you are using can only move data one way and then reverse. So when you are reading and writing you are basically turning it off and on.Using a second drive allows for the data to move one way and then the other on different cables. The nature of a serial drive.

Hey everyone, I just wanted to comment on this thread and say that if you have a dedicated video card, that is where you should see the performance gains with hardware acceleration. If you're video is integrated with your CPU you're more likely to see better performance with software-only acceleration.

With so many people having low
powered computers & integrated graphics.

Maybe there should be more
focus/warning when people install 2018 or render videos? I have a strong
graphics card so software-only acceleration is something I didn't have to know anything about.

Since TechSmith has chosen to enable
it by default. This creates quite a bottle neck
for a lot of users.

You may have a surprising number customers completely in the dark about this. If they don’t visit this forum or seek
support. How could they know? They might conclude that 2018 is a terrible
product compared to their other video editor.Or just on a hunch. Request a Refund, never upgrade
down the road. Or a whole host of possible negatives.
